THAT'S WHY THE SPF SHOULD MATCH YOUR NATURAL PROTECTION TIME
The natural protection time is the amount of time your skin can protect itself from sunburn without sunscreen. This time depends on various factors, such as your skin type, the intensity of the sun's rays, and the time of day. People with lighter skin have a shorter natural protection time compared to those with darker skin. By combining the SPF of a sunscreen with your natural protection time, you can determine how long you are protected from sunburn. Regardless of the SPF, sunscreen should be reapplied regularly, especially after swimming, sweating, or drying off with a towel, to maintain continuous protection.
